MOUTH-PIECE FOR WIND-INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 325,715, dated September 8, 1885. Application tiled March 25, 1884. (No model.)

To aZZ whom it may concern,.-

Be it known that I, OLIN A. WATSON, of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Mouth-Pieces for Musical Vind-Instruments, of which thefollowing is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying` drawings, forming a part of this specification.

The object of this invention is to provide a mouth-piece for Wind-instruments which is adapted to be adjusted so as to increase or diminish the depth of the cup by means of the pressure and relaxation of pressure from the lips of the player, as will be hereinafter more fully set forth and claimed.

Figure 1 is an elevation of a mouth-piece embodying my improved features; Fig. 2, a vertical central section in the plane 2 2, Fig. l; and Fig. 3 a side elevation of the tubular shank and cup.

Referring to the drawings, A represents an open cap-piece,- B, a ferrule, and C a tubular shank.

The tubular shank C is provided with the enlarged end D, the interior ofwhich is cupped out, forming the contracted cup a, as shown in Fig. 2. The exterior surface of the cup end D is provided with an annular groove for the reception of the packing-ring a', placed between the same and the interior surface of the cap A for the purpose of forming an airtight joint. The open cap A, having the rim a2, is provided with the exterior thread, a3, adapting the same to engage with the correspondingly-threaded interior surface, a, of the ferrule B,whereby these parts may be lengthened or shortened by turning the cap in or out, as may be required. The ferrule B is provided with the inwardly-projecting flange b, engaging with the under side of the enlarged which arrangement these parts are in proper relation and permit of a end D, by retained free longitudinal movement on the shank C independent of the screw-threaded adjustment of the cap and ferrule. The shank C is provided along a portion of its exterior surface with the screw-thread b, which receives the hand-nut cl, adapted 'to have a threaded connection with said shank. The spiral spring E encircles the shank C between the nut d and the ferrule B, the ends of the spring bearing on these parts, respectively. 'The tension of the spring is regulated by means of the handnut so as to suit different players. This construction and arrangement permit of the cap and ferrule being first adjusted so as to give the cup the required depth necessary to produce the lower notes, while a pressure from the lips of the player will force the cap and ferrule down on the shank, thus diminishing the depth of the cup and enabling the player to produce the higher notes, the spring serving to return the parts to a normal position when the pressure on the cap is relaxed.

It will be readily seen and understood with what convenience and facility the player is enabled to increase or diminish the depth of the cup without having to remove the lips from the mouth-piece, which is not the case where the adjustment is accomplished by a screw-threaded connection alone.

Having thus described my invention, what I claim as new, ,and desire to secure by Letters Patent, is-

In a mouthpiece as described, the combination, with the cap-piece A, of the ferrule B, provided with the inwardly-projeeting flange b, the tubular shank C, provided with the en` larged end D, the spiral spring E, and the tension-nut d, all constructed and arranged to operate as set forth.
